Valve yachipatandivalavu ya butterflyzonse zimagwira ntchito yosintha ndi kuwongolera kayendedwe ka kayendedwe ka mapaipi.Koma pali njira posankha mavavu agulugufe ndi mavavu a zipata.
Mu maukonde operekera madzi, pofuna kuchepetsa kuya kwa dothi lakuphimba payipi, valavu yagulugufe nthawi zambiri imasankhidwa pamapaipi okulirapo.Ngati ili ndi zotsatira zochepa pa kuya kwa dothi lophimba, yesetsani kusankha valavu yachipata, koma mtengo wa valve yachipata cha ndondomeko yomweyi ndi yapamwamba kuposa ya butterfly valve.Ponena za mzere wa malire a caliber, uyenera kuganiziridwa molingana ndi malo enieni a malo aliwonse.Malinga ndi momwe mavavu amagwirira ntchito m'zaka khumi zapitazi, kulephera kwa ma valve agulugufe ndikwambiri kuposa mavavu a pachipata, chifukwa chake ndikofunikira kukulitsa kuchuluka kwa kugwiritsa ntchito mavavu a pachipata ngati mikhalidwe ikuloleza.
Za ma valve a pakhomo M'zaka zaposachedwapa, opanga ma valve ambiri apanga ndi kutsanzira ma valve a zipata zofewa.Poyerekeza ndi ma wedge achikhalidwe kapena ma valve ofananira pazipata ziwiri, valavu yachipata ichi ili ndi izi:
1. Thupi la valve ndi bonnet ya valve yotsekedwa yotsekedwa yotsekedwa imaponyedwa ndi njira yolondola yoponyera, yomwe imapangidwa nthawi imodzi, makamaka sichifunikira makina opangira makina, sagwiritsa ntchito mphete yamkuwa yosindikiza, ndipo imasunga zitsulo zopanda chitsulo. .
2. Palibe dzenje pansi pa valve yotsekedwa yotsekedwa, ndipo palibe slag yomwe imasonkhanitsidwa, ndipo kulephera kwa chitseko cha valve kutsegula ndi kutseka kumakhala kochepa.
3. Chisindikizo chofewa chokhala ndi mphira chokhala ndi mphira chimakhala ndi kukula kofanana ndi kusinthasintha kwamphamvu.
Choncho, valve yofewa yosindikiza pakhomo idzakhala mawonekedwe omwe makampani operekera madzi akulolera kutengera.Pakali pano, m'mimba mwake wa mavavu ofewa osindikizidwa pachipata opangidwa ku China ndi mpaka 1500mm, koma awiri opanga ambiri ndi pakati 80-300mm.Padakali mavuto ambiri pakupanga m'nyumba.Gawo lofunika kwambiri la valve yotsekemera yotsekemera ndi mbale ya mphira yokhala ndi mphira, ndipo zofunikira zaumisiri wa mbale ya valve yokhala ndi mphira ndizokwera kwambiri, zomwe si onse opanga akunja omwe angathe kuzikwaniritsa, ndipo nthawi zambiri amagulidwa ndikusonkhanitsidwa kuchokera kwa opanga odalirika. khalidwe.
Chotchinga chamkuwa cha valavu yotsekera pachipata chofewa chimayikidwa pamwamba pa mbale ya valve yokhala ndi mphira, yomwe ili yofanana ndi kapangidwe ka valavu yachipata.Chifukwa cha kugwedezeka kwa nati, mphira ya mbale ya valve imasenda mosavuta.Makampani ena akunja amalowetsa chipika cha mtedza wamkuwa pachipata chokhala ndi mphira kuti apange zonse, zomwe zimagonjetsa zofooka zomwe zili pamwambazi, koma kukhazikika kwa kuphatikiza kwa chivundikiro cha valve ndi thupi la valve ndilokwera kwambiri.
Komabe, potsegula ndi kutseka chitseko chofewa chotseka chitseko, sichiyenera kutsekedwa mochuluka, malinga ngati madzi oletsa madzi akupezeka, mwinamwake sikophweka kutsegula kapena mphira wa rabara umachotsedwa.Wopanga ma valve amagwiritsa ntchito wrench ya torque kuti aziwongolera kuchuluka kwa kutseka pakuyesa kukakamiza kwa valve.Monga woyendetsa valve wa kampani yamadzi, njira iyi yotsegulira ndi yotseka iyeneranso kutsanziridwa.
Valve yachipata ndi chipata chotsegula ndi kutseka, kayendetsedwe ka kayendetsedwe ka chipata ndi perpendicular kwa kayendedwe ka madzi, ndipo valve yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu.Kuti apititse patsogolo kupanga kwake ndikupanga kupatuka kwa mawonekedwe osindikizira panthawi yokonza, chipata ichi chimatchedwa chipata chotanuka.
Pamene valve yachipata yatsekedwa, malo osindikizira angangodalira kupanikizika kwapakati kuti asindikize, ndiko kuti, kungodalira kupanikizika kwapakatikati kuti akanikizire kusindikiza pamwamba pa chipata ku mpando wa valve kumbali ina kuti atsimikizire kusindikiza kwa malo osindikizira, omwe ndi odzisindikiza okha.Ma valve ambiri a pakhomo amatsekedwa mwamphamvu, ndiko kuti, pamene valve yatsekedwa, chipata chiyenera kukakamizidwa kumenyana ndi mpando wa valve ndi mphamvu yakunja kuti zitsimikizire kuti malo osindikizira ali olimba.
Mayendedwe: Chipata cha valavu yachipata chimayenda molunjika ndi tsinde la valve, lomwe limatchedwanso kuti valavu yokwera.Nthawi zambiri, pali ulusi wa trapezoidal pa ndodo yokweza.Kupyolera mu nati pamwamba pa valavu ndi groove yotsogolera pa thupi la valve, kusuntha kwa rotary kumasinthidwa kukhala kusuntha kwa mzere, ndiko kuti, torque yogwiritsira ntchito imasinthidwa kukhala njira yoyendetsera ntchito.Pamene valve imatsegulidwa, pamene kutalika kwa chipata kuli kofanana ndi 1: 1 nthawi ya valavu, njira yamadzimadzi imakhala yosasunthika, koma malowa sangathe kuyang'aniridwa panthawi ya ntchito.Pogwiritsidwa ntchito kwenikweni, nsonga ya tsinde la valve imagwiritsidwa ntchito ngati chizindikiro, ndiko kuti, malo omwe sangathe kutsegulidwa, monga malo ake otseguka.Pofuna kuganizira zochitika zotsekera chifukwa cha kusintha kwa kutentha, nthawi zambiri zimatsegulidwa ku malo apamwamba, ndiyeno kubwerera ku 1 / 2-1 kutembenuka, monga malo a valve yotseguka.Choncho, malo otseguka a valve amatsimikiziridwa molingana ndi malo a chipata (ie sitiroko).Nati ina ya valavu ya pachipata imayikidwa pachipata, ndipo kuzungulira kwa gudumu lamanja kumapangitsa kuti tsinde la valve lizizungulira, zomwe zimapangitsa kuti chipata chikwere.Vavu yamtunduwu imatchedwa valavu yachipata chozungulira kapena valavu yachipata chakuda.
Kodi pali kusiyana kotani pakati pa valavu ya butterfly ndi valve valve?
Malinga ndi ntchito ndi kugwiritsa ntchito valavu yachipata ndi valavu yagulugufe, valavu yachipata imakhala ndi mphamvu zochepa zothamanga komanso ntchito yabwino yosindikiza.Chifukwa njira yolowera ya mbale ya valve ya pachipata ndi sing'anga ili pamtunda woyima, ngati valavu yachipata siinasinthidwe pamalo ake pa mbale ya valve, kukwapula kwa sing'anga pa mbale ya valve kumapangitsa kuti mbale ya valve igwedezeke., N'zosavuta kuwononga chisindikizo cha valve yachipata.
Valavu ya butterfly, yomwe imadziwikanso kuti flap valve, ndi mtundu wa valve yowongolera yokhala ndi mawonekedwe osavuta.Vavu ya butterfly yomwe ingagwiritsidwe ntchito poyang'anira paipi yapaipi yotsika kwambiri imatanthawuza kuti membala wotseka (disk kapena mbale) ndi disk, yomwe imazungulira kuzungulira shaft ya valve kuti ikwaniritse kutsegula ndi kutseka.Valavu yomwe ingagwiritsidwe ntchito poyang'anira kutuluka kwa mitundu yosiyanasiyana yamadzimadzi monga mpweya, madzi, nthunzi, zofalitsa zosiyanasiyana zowononga, matope, mafuta, zitsulo zamadzimadzi ndi ma radioactive media.Zimagwira makamaka ntchito yodula ndi kugwedeza paipi.Mbali ya gulugufe yotsegula ndi kutseka ndi mbale ya butterfly yooneka ngati diski, yomwe imazungulira mozungulira muzitsulo zake mu thupi la valve kuti ikwaniritse cholinga chotsegula ndi kutseka kapena kusintha.
Gulugufe mbale imayendetsedwa ndi tsinde la valve.Ngati itembenuza 90 °, imatha kumaliza kutsegula ndi kutseka kumodzi.Posintha mbali yowonongeka ya diski, kutuluka kwa sing'anga kumatha kuwongoleredwa.
Malo ogwirira ntchito ndi zoulutsira mawu: Mavavu agulugufe ndi oyenera kunyamula madzi osiyanasiyana owononga komanso osawononga m'makina a uinjiniya monga wopanga, gasi wamalasha, gasi wachilengedwe, gasi wamafuta am'mizinda, mpweya wotentha ndi wozizira, kusungunula kwamankhwala ndi kuteteza chilengedwe. , kumanga madzi ndi ngalande, etc. Pa payipi ya sing'anga, ntchito kusintha ndi kudula otaya sing'anga.
